Technical Specifications

Application in a photovoltaic installation

Stainless steel connectors are standard in photovoltaic installations not because of their appearance, but because the structure operates outdoors for several years. Galvanized components lose their coating more quickly in the same location, and replacing a single screw under the module means disassembling its mounting—the labor cost is many times greater than the difference in the price of the connector.

When assembling an installation, it's worth factoring in spare parts. Some connectors get lost on the jobsite, others need to be replaced when adjusting the row alignment, and buying a few more later is rarely cost-effective given the shipping costs. That's why we sell them in quantities tailored to actual installation usage, not individually.

Be sure to match the length to the thickness of the components being connected. A screw that's too short won't utilize the full height of the nut, while one that's too long will protrude beneath the module and may interfere with the frame or cabling running beneath the structure.

Washer din 125 m10 - what to pay attention to when choosing

When purchasing this item, check three things: compatibility with existing equipment on site, site conditions, and the quantity needed for the entire project. Photovoltaic system components operate outdoors for several years, in full sunlight and with fluctuating temperatures, so the choice of material and workmanship is crucial to the durability of the entire installation.

If you are collecting material for a specific installation, it is more convenient to take everything from one delivery - the remaining items from the same group can be found in the category of fasteners and clamps , and all surplus stock in the category of Stock.

Where does this stuff come from?

We sell inventory left over from closed projects and deliveries. The merchandise is brand new and covered by the same returns and refunds policy as the rest of our offerings. The only difference is that quantities are limited and will not be restocked—once the stock is depleted, the item will be removed from the store.

Minimum order and price calculation method

We sell this item from 100 pieces. The price listed for each item is for a single item, so the minimum order value is 100 times that amount. This threshold is based on inventory accounting: for small items, the time required to deduct and pack several items costs more than the item itself. However, when ordering a full package, this cost is spread across all items, allowing the unit price to drop that low.

The quantity ordered increases incrementally in the cart, so you can't accidentally place an order below the threshold. Above the threshold, you can purchase any number of items until stocks last—which is limited to what's left in stock.

Delivery and pickup

Orders are shipped from our warehouse. Shipping costs depend on size and weight—small items are shipped as a parcel, while items longer than a standard parcel require pallet shipping, which is visible in the shopping cart after adding items. For orders with multiple items, shipping costs are calculated once for the entire shipment, so collecting the materials for a single order is cheaper than shipping several items separately.

You can also collect the goods in person at our warehouse in Bytomiu — pickup is free. For low-value items, this is often the most reasonable option, as shipping costs can be as high as the order itself. It's worth confirming availability before arrival, especially for last-minute items.

A2 is the designation for stainless steel used in connectors – chosen in PV installations for its corrosion resistance after many years of use on the roof.

Do the elements fit profiles from other manufacturers?

These are standardized metric connectors. Check the thread dimensions and mounting space in your system to ensure they fit your specific profile.

Can I collect the goods in person?

Yes, personal collection in Bytomiu is free—you select it in your cart. For small items, this is often the most reasonable option, as shipping costs can be as high as the value of the item itself.
